Apply the medical improvement review standard (MIRS), which includes consideration
of both medical improvement (MI) and the exceptions to MI, to any adverse reopening
that would result in the termination of benefits or in a less favorable ending or
cessation date.
With rare exceptions, this means:
-
•
a determination of allowance or continuance may only be changed (based on medical
or vocational factors) to a determination of denial, closed period of disability,
or cessation; or
-
•
an ending date or cessation date may only be changed (based on medical or vocational
factors) to a less favorable date, if the case meets one of the group I error exceptions
or the group II fraud or similar fault exception to MIRS.
For more information on the effect of MIRS on reopening and revision and exceptions,
see DI 27501.005B.4. and DI 28020.000.
